Telkoor Capacitor Charging Power Supplies
Telkoor Power Supplies is a technical leader in switching power supplies for over 40 years.
Telkoor designed a family of capacitor chargers for pulsed laser applications,
(medical and aesthetic treatment) in the range 1500 / 2200W that provide high  efficiency,
fast response along with low EMI with no additional line filter required.
Main Features:
 Ideal for OEM Laser manufactures
 Low EMI
 High Efficiency
 Meets EN 55011 Conducted & Radiated Class A.
 Fully protected for overload, short circuit, over voltage over temperature.
 Load Fault Watchdog Timer can be modified upon customer request.
 Meet EN606011
 Can be modified upon customer request (voltage and output Power)
Advantages over exist chargers:
Telkoor capacitor chargers are a new design using the
Standard modular platform 12.7”x5.7”x4.1” that provide:
 Higher efficiency around 8% over the exist chargers, (reduced temperature rise, increased reliability).

Function at higher frequency and 50% duty cycle, (Fast response, less noise).

Shut down if the output voltage is equal or less than 80% of its maximum rate for more than 5 second (higher charge discharge cycle).

Fully isolated input to output (can be connected directly to the AC line).

Can provide per request up to 3KW using the standard platform.

Principle of operation
The capacitor charger tested as a charger that defined by charge time to charge a specific capacitor to requested voltage.
The capacitor charger has a three mode of operation as shown below
The rate of which the capacitor is charged and discharged is called the repetition rate , T , and may vary from 0.01Hz for large capacitor banks to a few KHz .
A capacitor charging has two power rating expressed in Joule per second (J/S)
The peak power rating is used when calculate the charge time and the average power is used to determine the maximum repetition rate.
The charge time calculated by using the formula:
T (second) =
Where:
T = Charge time in second
C = Capacitor in farads
V = Charge voltage require
Ppeak = Unit peak power (J/S)
The average output power depends on the discharge mode energy and repetition rate of the load.
P (average) (J/S) = Wload / T
T= repetition rate .
w= energy delivered per charging cycle.
